Filling out brackets: 7-10 and 6-11 games

Charissa Thompson offers advice on filling out your bracket.

We recap our best notes from the 7-10 and 6-11 matchups in the 2012 Men's Basketball Championship. Check this blog and check here all week for more bracket tips.

• A 10-seed has beaten a 7-seed at least once every year since the field expanded to 64 teams in 1985 except: '85, '93 & 2007. The only year all four 7-seeds lost in the Round of 64 was 1999.

Notre Dame (7-seed) and Xavier (10-seed) met once before in the Men’s Basketball Championship, a 71-83 win by Notre Dame in 2001 in the Round of 64.

• The Fighting Irish are 19-0 when assisting on more than 60 percent of their field goals (3-10 when they do not). Xavier's A-10 opponents assisted on 59.7 percent of their field goals.

• The Biggest BPI differential in the 7-10 matchups is between 7-seed Gonzaga (21 BPI) and 10-seed West Virginia (42 BPI).

Florida averages 1.16 points per possession this season, tied for fourth-highest in the nation. Virginia allows 0.88 points per possession, the second-lowest in the nation.

• Florida is 18-3 this season when making 10 or more 3-point field goals -- one of the losses was against Kentucky and one was against Ohio State (Gators are 5-7 when making fewer than 10 3-pointers). Virginia has only allowed one opponent to make 10 or more 3-point field goals this season.

• West Virginia averages 14.9 second-chance points per game this season, the most in the Big East. Gonzaga led the West Coast Conference in defensive rebounding percentage (73.3) during conference play.

Purdue allowed 1.09 points per possession during conference play, its most in the past 10 seasons. Saint Saint Mary's averages 1.16 points per possession, tied for eighth-most in the nation.

• Only one 7-seed has reached the Final Four since 1979 (Virginia in 1984), but three 11-seeds have made it that far: VCU last year, George Mason in 2006 and LSU in 1986.

• With the exception of 2004, an 11-seed has won at least one tournament game every year since 2000.

• The closest 6-11 matchup according to BPI is 40th-ranked San Diego State against 45th-ranked NC State.

• Is this an upside-down 6-11 game? BPI ranks Texas 25th. That translates to a 7-seed but the Longhorns are an 11. They play Cincinnati, which is 36th in the BPI.

• The biggest 6-11 mismatch according to BPI is UNLV (ranked 28th) against Colorado (87th). Murray State (36) against Colorado State (70) is next.
